C, and may also pass through the top iloor A ot' the car. Collars may be attached to the oors to give `additional support to the pedestals.

When the wheel-bearing pedestals are placed in position they hold the slide-beams from moving. When it is desired to permit the slidebeams to move, as would be the case with center bearing-wheels under a long car, a slot 0r opening is made in the under floor t'or the movement ot' the pedestal, and the pedestal is fastened to the slide-beam only.

Operation: To use the car on a common railway, have singleanged or common car- Wheels, and fasten the pedestaiarms so that the pedestals cannot revolve. To work it as a platform-car, place the wheels at the four corners et' the car. To use it as an end-dumper, place the two Wheels at the center ot' the sides ot' the car, and two at the end opposite to that from which it is desired to dump, as shown in Fig. 2. Load so that car will not dump of itself', but have the principal weight bear on the center wheels. To dump at the side, place two wheels at the center of the ends of the car, (two on the end of two slidebealns,) have the center wheels and center of the car over one rail, and draw out one or two sldebealns and lasten them, so that their wheels will rest on the opposite rail, as shown in Fig. 5. Load so that the wheels on the end of the slide-beam will carryonly enough Weight to prevent selfvdumping.

At the point of dumping a piece of plank or rail may be spiked to ties, as shown in Fig. 5, to keep the single-anged wheels under the center of the car from sliding ol the rail.

To use the car on a single mainfrail track, with either one or two side supports-it' on track without hard curves, single anged Wheels may be used, and the car operated the same as on an ordinary railway; but on curves of very short radius use double-anged guidewheels, with pivoted pedestals on the main rail, and nnanged balancing-wheels 0n the auxiliary rails, so as to avoid friction in curving. Have the gage ot the outside or auxiliary rails right for the outside Wheels of the car, and the main rail in the center, as shown at Fig. 3.

For a platform or non-dumping car, place a double-flanged guide-Wheel under the center of each end ot' the car, over the main rail, and a balancing-wheel under the center of each side of the car, or in either of the other loca.- tions, as may be most convenient.

For dumping, change the location of wheels, as on ordinary two-rail track. At the dumpin g-point, a depression of the end of the track, for end-dumping, or a depression of .one rail or elevation of the opposite rail, forside-dumping, will cause the car to dump Without assistance, and I have found by experiments with heav loads on this car that, inclining the wheels with the car, for dumping, will not throw the main wheels from the rail or strain or injure the car.

I claim as my invention- 1. In a railwayear for a single rail track, the pivoted pedestal F, in combination with the doubletlanged Wheel E, arranged substantiall)` as described.

2. The brace-arms M M, or their equivalents, on the pivoted pedestal F, with or without the grooved sockets G, substantialbY as and for the purposes described.

3. In combination with the pedestal F and arms M M, the grooved guides G, or their equivalents, arranged substantially as and for the purposes described. y

4. In a dumping railway-car, the sliding adjustable beams C (J, arranged substantially as described.

5. In combination with the sliding beam O and pedestal F, the clamp K, 0r its equivalent, substantially as and for the purposes described.
